What does circumcising men do to women’s HIV risk?



Advocates for mass male circumcision have paid insufficient attention to protect women. Here are two ways these programs increase women’s risks for HIV.

Not protecting women from high risk to get HIV from a newly circumcised, HIV-positive partner

Only one study has followed wives of newly circumcised HIV-positive men to see what happens to their wives. That study, in Uganda, 2003-07, circumcised some HIV-positive men and left others intact, and then followed and tested their wives from time to time to see who got HIV. Over several years, wives of men circumcised for the study were 1.49 times more likely to get HIV than wives whose husbands remained intact (see Table below). Wives of circumcised men were at especially high risk if they resumed sex before their husbands’ circumcision wound healed – 5 (28%) of 18 who did so got HIV within 6 months after their husbands were circumcised.
Despite this risk, UNAIDS recommends: “The offer of male circumcision should neither depend on a person undergoing an HIV test, nor on a person being…HIV-negative.”[i] Donors and governments follow this advice – circumcising men without requiring them to take an HIV first and, if found to be HIV-positive, to bring their wives for couple counseling before proceeding with the circumcision.

Allowing women (and men) to think sex without condoms with a partner who may be HIV-positive is safe

Such beliefs conflict with available evidence. According to three studies, even with healed wounds, circumcised men transmit HIV to women. Whether they do so faster or slower than intact men is unknown. Two out of 3 studies that followed discordant couples — with HIV-positive men and HIV-negative wives – report that intact men transmit faster than circumcised men. The third study reports the opposite: that circumcised men transmit faster than intact men — not only in the first 6 months after circumcision, but continuing for the next 18 months as well (when the study ended).
Faster or slower? The jury is out. But what is clear from these studies is that women who want to be safe — not just safer — need to continue to use condoms with men who may be HIV-positive, whether they are circumcised or intact.
